Patent number: 11234444Abstract: The continuous pasteurization system (100) that pasteurizes raw food products (104) while substantially maintaining the raw state of the raw food products includes a conveyor (102) on which the raw food products (104) are loaded for delivery to a pasteurization apparatus 36, wherein the raw food products are quickly heated so that the temperature of the outer surface of the raw food products is raised sufficiently to achieve a desired pathogen kill level. Thereafter, the raw food products (104) are immediately cooled in a cooling apparatus (110) to remove the heat applied to the raw food product and maintain the substantial raw state of the raw food product. A control system (24) is connected to a processor (30) as well as various measuring devices and instruments, including temperature measurement devices (T1-T5) to control the operation of the pasteurization system (100).Type: GrantFiled: April 26, 2016Date of Patent: February 1, 2022Assignee: John Bean Technologies CorporationInventors: Ramesh M.

Patent number: 11118787Abstract: An impingement oven (40) includes an upper housing structure (46) forming the exterior of the upper half of the impingement oven and a lower housing structure (48) to mate with the upper housing structure. An interior impingement housing (62) is positioned interior to the upper and lower housing structures (46) and (48). A conveyor (60) extends through the interior impingement housing (62). The inside surfaces of the upper and lower housing structures (46) and (48) cooperate with the interior impingement housing (62) to define upright supply chambers (80a) and (80b) on opposite sides of the impingement oven to direct cooking medium downwardly upon the work products being carried by the conveyor and also upwardly through the porous belt of the conveyor, thereby to thermally process the work products being carried on the conveyor.Type: GrantFiled: September 23, 2016Date of Patent: September 14, 2021Assignee: JOHN BEAN TECHNOLOGIES CORPORATIONInventors: Owen Eugene Morey, Ramesh M.

Patent number: 10602759Abstract: A thermal processing and control system (300) includes a thermal processing station (312) for receiving food products (14) being carried on a conveyor system (316). A first scanning station (318) is located upstream from the thermal processing station (312) for scanning the food products being carried by the conveyor (316). An actuator (420) automatically connects temperature measuring devices (402) with selected food products (14). A diverter conveyor (324) diverts selected food products (14) from the conveyor (316) to a transverse conveyor (326) for either further processing or alternative processing, depending on how system (300) is configured.

Patent number: 8753703Abstract: An process for cooking bacon includes the steps of continuously feeding bacon strips in three or more rows to an inlet of a spiral cooking oven, moving the bacon strips along a spiral path inside the spiral oven, applying a cooking fluid into the spiral oven and through the spiral path, and cooking the bacon strips in the spiral oven to a yield percentage having a mean bandwidth variation not greater than 4.5%. A conveyor belt having variable weaving includes belt openings that are initially larger through an inner side of the belt than through an outer side of the belt, when the belt is straight. When the belt collapses into the spiral configuration, the openings adjust so that the areal size of the openings is similar on both lateral sides of the belt, resulting in more even distribution of cooking fluid and more uniform cooking.Type: GrantFiled: October 23, 2009Date of Patent: June 17, 2014Assignee: John Bean Technologies CorporationInventors: Ramesh M.

Patent number: 8707861Abstract: An apparatus for pasteurizing a dry food product comprises an impingement chamber, a conveyor for conveying the dry food product through the impingement chamber; a heater and water supply assembly for generating heated, moist air, and a fan for circulating the heated, moist air through the impingement chamber and onto the dry food product. In operation, the moisture in the heated, moist air condenses on the surface of the dry food product and produces a heat of condensation which heats the surface of the dry food product. Moreover, this heat of condensation is sufficient to kill a percentage of any pathogenic microorganisms which may be present on the surface of the dry food product.Type: GrantFiled: July 22, 2005Date of Patent: April 29, 2014Assignee: John Bean Technologies CorporationInventors: Ramesh M.
